It’s the law!Condensate treatment is not only the responsible thing to do, in most countries it’s the law! Non-compliance can result in hefty fines.

Effective and effortless condensate treatment An oil-water separator removes the oil from your compressor condensate before it can enter the sewage system. However, too many oil-water separators offer subpar quality and minimal ease of use. Atlas Copco’s OSC series allows you to comply with local regulations and to protect the environment with unmatched filtration precision and zero-hassle maintenance.

Highly efficient multi-stage filtration 1. The condensate enters the unit via one single or multiple

inlets. It passes through a diffuser and depressurizes in the expansion chamber. The diffuser removes bigger solid particles from the condensate so that these cannot compromise the filter media.

2. The oil-water mixture continues to the first filter chamber. It seeps through the polypropylene filter, which adsorbs the oil, but not the water.

3. The condensate remains in the chamber for a while, starting a secondary, natural filtration as the remaining free oil floats to the top and is adsorbed by the filter bag.

4. Significantly cleaner condensate flows into the second chamber.

5. A removable cartridge, filled with activated carbon (or organoclay for stronger emulsions), separates the remaining oil droplets from the condensate.

6. Clean condensate exits from the removable cartridge with almost no residual oil content, allowing for safe discharge into the sewer system.
